Abstract:
Hydantoins and their sulfur containing analogues, thiohydantoins, are cyclic ureides that have attracted huge attention ever since their discovery. Most of them are biologically active compounds and several points of structural diversity have made them very synthetically attractive. Although substituents can be introduced to the hydantoin nucleus, most substituted hydantoins are synthesized from substrates already containing these groups, while forming the hydantoin nucleus. This is a common route to the synthesis of hydantoins and one of them is employed in this study. A series of 3-allyl-2-t

Abstract:
A synthetic route involving a hydantoin derivative of bicyclo [3.2.0]hept-2-ene has been investigated for the preparation of neurotransmitter analogues containing an additional acetic acid substituent on the cyclobutane ring of the potent NMDA receptor agonist trans-1-aminocyclobutane-1,3-dicarboxylic acid. X-Ray analysis showed that the major cyclobutane amino acid produced had the 2-acetic acid and 3-carboxylic acid substituents in the trans orientation as a result of epimerization during hydantoin hydrolysis.

Two series of fused tetrahydro-β-carboline hydantoin and tetrahydro-β-carboline thiohydantoin derivatives with a pendant 2,4-dimethoxyphenyl at position 5 were synthesized, and chiral carbons at positions 5 and 11a swing from R,R to R,S, S,R, and S,S. The prepared analogues were evaluated for their capacity to inhibit phosphodiesterase 5 (PDE5) isozyme. The R absolute configuration of C-5 in the β-carboline hydantoin derivatives was found to be essential for the PDE5 inhibition.

Abstract:
This article presents methods for synthesis of 3-amino derivatives of cyclohexanespiro-5-(2-thiohydantoin) and cyclohexanespiro-5-(2,4-dithiohydantoin). It was found out that the treatment of cyclohexanespiro-5-(2-thiohydantoin) with hydrazine hydrate under different reaction conditions led to obtaining of 3-amino derivative and 2-hydrazone of the initial compound. As a result of thionation of 3-aminocyclohexanespiro-5-hydantoin with P4S10 or Lawesson’s reagent, the corresponding dithio-analogue was synthesized. The structures of the products obtained were verified by IR, 1H NMR, 13C NMR and m

Indoles and hydantoins are important heterocycles scaffolds which present in numerous bioactive compounds which possess various biological activities. Moreover, they are essential building blocks in organic synthesis, particularly for the preparation of important hybrid molecules. The series of hybrid compounds containing indoles and imidazolidin-2-one moiety with direct C–C bond were synthesized using an amidoalkylation one-pot reaction. All compounds were investigated as a growth regulator for germination, growth and development of wheat seeds (Triticum aestivum L). Their effect on drought r
